Description

Technical Field

[0001] This utility model relates to the field of mold blank hoisting, specifically a mold blank hoisting fixture for mold processing. Background Technology

[0002] A mold blank lifting fixture is a special tool used to move mold blanks during mold processing, which can improve handling efficiency and ensure operational safety.

[0003] In existing technologies, a threaded fixing rod is typically used to pass through a slot and then be threaded to a nut to achieve the connection function. After the mold blank is transferred to another position, the connection between the lifting fixture and the mold blank is released by loosening the nut. This method is inefficient. Utility Model Content

[0004] The purpose of this utility model is to provide a mold blank hoisting fixture for mold processing in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mold blank lifting fixture for mold processing, including a lifting ring, the lifting ring being connected to a lifting device via a sling, a downwardly protruding fixing rod integrally formed at the bottom of the outer wall of the lifting ring, a limiting mechanism axially slidingly installed inside the fixing rod and penetrating to the outer wall of the fixing rod, and an unlocking mechanism vertically slidingly installed inside the fixing rod, the bottom end of the unlocking mechanism penetrating to the bottom of the fixing rod, the unlocking mechanism being used to drive the limiting mechanism to retract into the interior of the fixing rod.

[0006] As a further improvement of this utility model: a receiving groove is provided inside the lower part of the fixed rod to accommodate the limiting mechanism and the unlocking mechanism.

The end of the limiting block located outside the fixing rod has a first pressure inclined surface. The end of the limiting block located inside the fixing rod is fixedly connected to the inner wall of the receiving groove with a spring.

[0008] As a further embodiment of this utility model: the unlocking mechanism includes a sliding plate that is vertically slidably installed inside the horizontal groove of the receiving groove. The top two ends of the sliding plate protrude inward, and the ends of the sliding plates that are close to each other are formed with an extrusion bevel. The bottom end of the horizontal plate of the sliding plate is integrally formed with a sliding rod that is vertically slidably installed inside the vertical groove of the lower half of the receiving groove.

[0009] As a further embodiment of this utility model: the unlocking mechanism includes a pressure block integrally formed on the bottom end of the limiting block, the pressure block is located in the inner cavity of the receiving groove, and the bottom end of the pressure block is formed with a second pressure slope that matches the extrusion slope.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-3 In this embodiment of the utility model, a mold blank hoisting fixture for mold processing includes a lifting ring 1. The lifting ring 1 is connected to the hoisting equipment via a sling 2. A downwardly protruding fixing rod 3 is integrally formed at the bottom of the outer wall of the lifting ring 1. A limiting mechanism that penetrates to the outer wall of the fixing rod 3 is axially slidably installed inside the fixing rod 3. An unlocking mechanism is vertically slidably installed inside the fixing rod 3. The bottom end of the unlocking mechanism penetrates to the bottom of the fixing rod 3. The unlocking mechanism is used to drive the limiting mechanism to retract into the interior of the fixing rod 3. A receiving groove 6 is provided at the bottom of the interior of the fixing rod 3 to accommodate the limiting mechanism and the unlocking mechanism. The upper part of the receiving groove 6 has a vertical cross-section with an open top in the shape of a "C" shape. The lower half of the receiving groove 6 is a vertical groove that penetrates to the bottom end of the fixing rod 3.

[0018] In this embodiment: First, when the mold blank is lifted, the bottom of the fixing rod 3 is aligned with the hole groove on the mold blank (the hole groove is a through hole for connecting the mold blanks, and the through holes of the two mold blanks are aligned for bolt insertion and nut connection). During the insertion of the fixing rod 3, the limiting mechanism is retracted under force until the limiting mechanism moves to the bottom of the hole groove. At this time, the limiting mechanism pops out to achieve hooking, and the mold blank can be lifted and transferred by the lifting equipment.

[0019] After the transfer, when the mold blank needs to be disassembled, the upward pressure is applied to the unlocking mechanism to push the driving limit mechanism into the receiving groove 6, and the fixing rod 3 can be pulled out.

[0020] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The limiting mechanism includes two limiting blocks 4 that are axially slidably installed in the two upper vertical grooves of the receiving groove 6. The ends of the two limiting blocks 4 that are far apart from each other extend to the outside of the fixing rod 3. The end of the limiting block 4 located outside the fixing rod 3 has a first pressure inclined surface. The end of the limiting block 4 located inside the fixing rod 3 is fixedly connected to the inner wall of the receiving groove 6 with a spring 7.

[0021] In this embodiment: during the insertion of the fixing rod 3, the bottom first pressure inclined surface of the limiting block 4 is subjected to extrusion force, driving the limiting block 4 to retract into the receiving groove 6. At this time, the spring 7 is compressed until the fixing rod 3 drives the limiting block 4 to move below the hole groove. At this time, the spring 7 resets and pushes the limiting block 4 to pop out, achieving the hooking effect, so that the mold blank can be transferred by the lifting equipment.

[0022] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The unlocking mechanism includes a sliding plate 9 that is vertically slidably installed inside the horizontal groove of the receiving groove 6. The top two ends of the sliding plate 9 protrude inward. The ends of the sliding plates 9 that are close to each other are formed with a pressing slope. The bottom end of the horizontal plate of the sliding plate 9 is integrally formed with a sliding rod 5 that is vertically slidably installed inside the vertical groove of the lower half of the receiving groove 6. The unlocking mechanism includes a pressure block 8 integrally formed at the bottom end of the limiting block 4. The pressure block 8 is located in the inner cavity of the receiving groove 6. The bottom end of the pressure block 8 is formed with a second pressure slope that matches the pressing slope.

[0023] In this embodiment: after the mold blank is transferred to the predetermined position, an upward squeezing force is applied to the sliding rod 5, which pushes the sliding plate 9 to move upward. At this time, the squeezing slope squeezes the second pressure slope, and the two pressure blocks 8 move towards each other. The movement of the pressure blocks 8 drives the limiting block 4 to move synchronously and retract into the receiving groove 6, thus realizing the unlocking function.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
